I used wire from the heater from the heater with glass tubes.In my state is called a heat lamp.One heater cost U.S. $ 1.Since a heater you can make 7-8 knife heaterstriangle shaped knives for a number of frames.With the wire at 12 v is remarkable.It takes more skill because you are working with him as with a hand saw.12 V is still a small number of frames, the only advantage is that you can trim what to do when you roll conditions and put in a jar.When you open frame horizontal hold.

Sorry for the bad shot, bad explanations.My Internet connection is very bad, shot in a small format so that I can more easily released.I live in a small village in Serbia, near the river Drina.Here is a very bad connection.The pictures are very clear, but the frame shown is DB, the torus.Cable length corresponds to a beekeeper who has special hive.The video frames uncovered small DB.
